A Windows Communication Foundation (WCF) service uses the following service contract.
[ServiceContract]
public interface IService
{
[OperationContract]
string Operation 1 (string s);
}
You need to ensure that the operation contract Operationi responds to HTTP POST requests.
Which code segment should you use?

• A. [OperationContract| [Weblnvoke(Method POST)] string Operationl(string s);
• B. [OperationContract| [WebGet(UriTemplate = POST')] string Operation 1 (string s);
• C. [OperationContract(Action WPOST)1 string Operationl(string s);
• D. [OperationContract(ReplyAction z 'POST')J string Operationi (string s);

A WCF service code is implemented as follows. (Line numbers are included for reference only.)
01 <ServiceContract()> 02 <ServiceBehavior( 03 InstanceContextMode:=InstanceContextMode.Single)> 04 Public Class CalculatorService 05 06 <OperationContract()> 07 Public Function Calculate(ByVal op1 As Double, 08 ByVal op As String, ByVal op2 As Double) As Double & 24 End Function 25 26 End Class
You need to decrease the response time of the service.
What are two possible ways to achieve this goal (Each correct answer presents a complete solution? Choose two.)

• A. Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
• B. Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
• C. Require the clients to use async operations when calling the service.
• D. Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.

You are developing a client application that consumes a Windows Communication
Foundation (WCF) service. The operation contract is as follows.
<OperationContract()>
<FaultContract(GetType(SalesFault))>
Function GetSales(ByVal saieId As String) As String
The service configuration file contains the following line in the serviceBehaviors section.
<behovior>
oerviceDebug includeExceptionDetoilInFaults-"True'V>
</behavior>
A divide-by-zero exception is not being handled by the service.
You need to ensure that the exception is caught in the client application.
Which type of exception should the client catch?

• A. FaultException
• B. TimeoutException
• C. FaultException(Of SalesFault)
• D. DivideByZeroException

A Windows Communication Foundation (WC9 service implements a contract with one-way and requestreply operations.
The service is exposed over a TCP transport Clients use a router to communicate with the service. The router is impemented as follows.
(Line numbers are included for reference only.)
01 Dim host As ServiceHost = 02 New ServiceHost(GetType(RoutingService)) 03 hostAddServiceEndpoint(
04 GetType(lSimplexDatagramRouter),
05 New NetTcpBinding0, "net.tcp://localhostlRouter"
06)
07 Dim lep As List(Of ServiceEndpoint) =
08 New List(Of SenviceEndpointx)
09 lepAdd(
10 New ServiceEndpoint(
11 CortractDescription.GetContract(
12 GetType(lSimplexDatagramRouter)
13)1
14 New NetTcpBinding0,x
15 New EndpointAddressf'nettcp://localhost:8080/Logger')
16)
17)
18 Dim rc As RoutingConfiguration = New RoutingConfiguration()
19 rc . FitterTable.Add(New Matctf4llMessageFilter0, lep)
20 host. Description. Behaviors.Add(New RoutingBehavior(rc)) Request-reply operations
are failing.
You need to ensure that the router can handle one-way and request-reply operations.
What should you do?

• A. Change line 12 as follows
  GetType(lRequestReplyRouter)
• B. Change line 04 as follows
  Get Type(lDuplexSessionRouter),
• C. Change line 04 as follows.
  Get Type(lRequestReplyRouter),
• D. Change line 12 as follows.
  Get Type(IDuplexSessionRouter)

Request-reply operations are failing.
You need to ensure that the router can handle one-way and request-reply operations.
What should you do?

• A. Change line 10 as follows. typeof(lDuplexSessionRouter)
• B. Change line 10 as follows. typeof(lRequestReplyRouter)
• C. Change line 03 as follows. typeof(lDuplexSessionRouter),
• D. Change line 03 as follows. typeof(l RequestReplyRouter),
